Why Mid-Cap Magazines?Mid-Capacity magazines offer stealth operation by eliminating BB rattle often experienced with Hi-Caps. They feed smoother than Hi-Caps due to their high tension internal spring, similar to a real steel magazine. Since 470 round Hi-Capacity magazines don't exist in real life, a good amount of Mil-Sim players prefer Mid-Cap magazines for an even more realistic type of gaming experience.

Due to the design of all Mid-Cap magazines, they actually function better once you break them in. To do so spray some light silicone oil into the magazine, load and unload it a few times until BB's feed smoothly. This process breaks in the internal spring allowing it to function without problems each and every time.

"I personally have a history with KA quality with their BBs. Those fed like no other, let me tell you. The qualities of those BBs set higher expectations of King Arms for me so when I got these mags, these were no exception. I got five total and all five hit everything I wanted exactly with the additional plus of it having just about zero wobble. Although it's no full metal 190rdyou AIMTOP midcap, the build and feed quality of this mag personally spike above others in my opinion. I'm going to get 3 more very soon for a total of 8 KA midcaps + 3 Aimtop 190rd midcaps. I recommend to any and all airsofters considering King Arms.

"I bought three of these for my custom m4, plastic body, everything internally is upgraded, 400fps, around 850rpm. They all worked for about one game, then two of the three would not feed at all, while the other one worked perfectly fine. They seem to be very durable, given the fact that after they would stop feeding in the middle of a firefight, i would throw them against the nearest rock, and they only have a few scratches. Throwing them did not break them, as they still work in my friend's g&g raider XL, and his vfc m4.

Pros:
Throw proof, very durable
nice capacity
don't rattle
black, not a grey like some others
ok price
don't wobble in gun
great to relieve stress if you need to throw something

Cons:
Stopped feeding after one game
Gets you killed in a firefight

3/5 since they are very durable, and they seem to work in some guns, but not all.

I do NOT recommend these, the EliteForce ones are just as good, cheaper, and feed in my gun along with my friend's vfc and g&g

"Recently purchased this for my G&G combat machine custom. I'd like to say it DOES fit on my G&G gun with very little wobble. It feeds great on semi and full auto. The only thing I could say against this is that its really light. Its still sturdy, but its so light its almost unrealistic! But that could be a pro also because it lessens the overall weight of the gun. If you are an airsofter on a budget, get this!
